IMO one of the reasons that intake plenum is so swept forward is the need to free as much space as possible at the back of the V for the new compressor air duct... The new turbo seems to be much compact and closer to the PU, and the new compressor's intake has been placed inside the V, à la Ferrari, IMO
(while it was outisde in 2014-2016)...
And maybe that plenum hides a small air-water intercooler too... or a diaphragm-like system
So I was right... except for the red part
As you can see, the compressor's airbox is now located forward of the engine's rear mounting points. That means the whole turbo hase been pushed forward. The red-capped disc-shaped airbox seems to hang inside the V.. well almost.
And the intake plenum bends forward to clear the way for the airbox... A 2014-2016 plenum would sit on the 2017 compressor inlet.
Couldnt find a good pic, but the 2014-2016 PU had its airbox aft the v6 mounting point so outside the engine.
So 2017 engine "2nd gen" is shorter/more compact.
Which, on paper, brings some benefits regarding weight distribution, pipework/lag, gearbox size/aero etc
